In today's scenario, the utility power available has,
unfortunately, several unwanted parameters like sags, surges, voltage variation,
frequency variation, brownouts, spikes, dips, blackouts,etc.
However, with more and more sensitive and demanding equipment being deployed by
the day, the need for clean power has become all the more essential in order to
ensure its correct functioning and to afford total protection.
Elnova On-Line Ups Systems offer clean power and total protection to your costly equipment.
These state-of-the art Double Conversion type UPS Systems employing High
Frequency PWM Technique using MOSFET/IGBT as the Main Switching Device for
inverters are technically superior UPS system giving Pure Sine Wave Output.
Compact and well engineered, Elnova On-Line UPS have been tried and tested in virtually
all applications, and have been found to be extremely reliable and consistent in delivering
optimum performance. These systems, besides being easy to install and operate, are simple to
maintain, should the need ever arise.
This range of UPS Systems is brought to you by Elnova. Promoted by technocrats having wide
experience in the field, Elnova today is an established company with country-wide sales and
service network and a product range that commands an enviable record of high MTBF and low MTTR.
